I got to drive the hyper some more, damn good it is. I absolutely love the way it drives, I think the spider-diffs are what makes it so good. It also makes a very different sound to my buggies.
I hope this dry weather holds so I can play with it some more.
The diffs are set up f-5k c-10k r-3k and the tires are some very cheap premounts with square flat spikes.
I promised pictures so here is my hyper:
You can se that the center spider-diff is scraped up.

Here you can se my new big-bores I bought for this car, and some hand porn for those who like that.(You know who you are;-))
